The second edition of this excellent book brings many new features, which were outlined in the preface to the 2nd Edition. The pursuit of the golden balance between oversimplification and overload with theory has always been the primary goal of every author of book on rheology. Rheology is a tool for chemists and chemical engineers to solve many practical problems. They have to learn what to measure, how to measure, and what to do with the data. But, the learning process should not take users away from their major goals, such as manufacturing quality products, developing new materials, analysis of material durability.The first four chapters of this book discuss various aspects of theoretical rheology and, by examples of many studies, show how particular theory, model, or equation can be used in solving different problems. The main emphasis is on liquids but solid materials are discussed in one full chapter.The goal of rheological studies is not to measure some rheological variables but to generate relevant data and this requires experience and understanding of theory. The authors share their experiences of many years of experimental studies and teaching to show use of rheology in studies of materials. This is one very strong aspect of this book which will help to avert costly confusions - common when data are generated under wrong conditions or data are wrongly used.Methods of measurement and raw data treatment are included in one large chapter which constitutes over one quarter of the book. Eight groups of methods are discussed here giving many choices for experimentation and guidance on where and how to use them properly.The final chapter shows how to use rheological methods in different groups of products and methods of their manufacture. Usefulness of chemorheological (rheokinetical) measurements is also emphasized. This chapter continues with examples of purposeful applications in practical matters.The authors were very meticulous in showing historical sequence of developments which led to the present advancements in rheology. This aspect is of interest of specialists in rheology, professors and their students because it shows in chronological order important events and teaches about their implications on further discoveries. References to various chapters and short summaries of achievements of many scientists give essential historical background of contributors to rheology as a science and as the method of solving many practical problems.Many people need this book, ranging from students to accomplished rheologists because it contains expert advice of two very famous and accomplished scientists and teachers who know discoveries first-hand because they may have taken part in some of them and they intent to pass their knowledge to the next generations.

This book is very useful in industry but it is invaluable as a teaching tool in universities and colleges because it is consistent with programs of rheology courses. Practicality of this book will prepare students for typical tasks in industry.

Preface to the 2nd EditionIn preparing the Second Edition of this book, the general structure of the book is maintained and some necessary corrections and additions are made. The most important recent results published in periodicals till the middle of 2011 are added. In particular, Section 2.8.1 of Chapter 2, Section 3.5.2 of Chapter 3 and Subsection 5.8.1.2 of Chapter 5 are modified. A new Subsection 5.6.2.6 on Capillary breakup in elongational rheometry is added. Furthermore, Section 3.2.3 on Viscosity of anisotropic liquids and Section 3.6.3 on Instabilities in flow of elastic fluids of Chapter 3 are completely rewritten. Many other modifications in the text are made and some new figures are added. Also, all the detected misprints and errors found by ourselves or pointed out by colleagues are corrected. After publication of the First Edition of the book, a lot of comments and advice from our friends and colleagues were received. We are very grateful to all of them for constructive criticism and valuable comments.We are also grateful to our Editor, Dr. G. Wypych, for his hard work in improving the manuscript and making it ready for publication.
